Masonry homes and walls constructed of brick and stone can develop<\/p>\n
voids, cracks, crumbling mortar, or uneven areas of mortar from settling<\/p>\n
or foundation problems. Separations between brick and mortar can allow<\/p>\n
air and water to leak through gaps in the wall. Repairing cracked mortar is<\/p>\n
called tuck-pointing.<\/p>\n
Tuck-pointing is typically needed when exposure (of 25-30 years) causes<\/p>\n
mortar joints to crack, flake, or disintegrate. Large holes and washed out<\/p>\n
mortar are typical signs that tuck-pointing is needed.<\/p>\n
Although the right material and technique are usually enough to deliver a<\/p>\n
water-tight job, it usually takes the skill of experienced professionals to use<\/p>\n
the proper mortar mix and tools to match existing mortar.<\/p>\n
The U.S. Department of the Interior Office of Historic Preservation has<\/p>\n
established<\/p>\n
standards to preserve the appearance of older buildings and to avoid<\/p>\n
irreparable<\/p>\n
damage during repointing and in the future. Often modern hard cement mortar<\/p>\n
cannot<\/p>\n
be used in older buildings because applying modern mortar over old lime<\/p>\n
mortar can<\/p>\n
result in serious damage to the original building materials and may not<\/p>\n
last. It is<\/p>\n
important that new mortar match the original in porosity and compressive<\/p>\n
strength.<\/p>\n","protected":false},"excerpt":{"rendered":"
